| Description: Longitude is the angular distance east or west from the defined central or prime meridian. The longitude_resolution attribute indicates the minimum difference between two adjacent latitude values expressed in angular units of measure. For raster data, the value is normally the pixel size in angular units (currently degrees). For vector data (points, lines, polygons), it is a little less concrete and usually indicates the fuzzy tolerance or clustering/streaming setting that establishes the minimum distance at which two points will NOT be automatically merged during data collection. This should also be reported in angular units (currently degrees). |
